I shoot @ 12 power on my Sidewinder. ALWAYS. I'm not big on changing magnification as, for my eyes, there's no need for it. That's the magnification I have Strelok set up for so that's where I leave it. Maybe that's why I seem to have less "problems" with the camera. Although, yesterday I was trying to get a video of a squirrel shot @ 120 yds & when I reviewed the video at home the bottom of the field of view was cut off. Must have knocked it out of whack at some point. Live and learn. From your posts I get the impression you change magnification a lot.
